One of the most stressful situations for a driver is dealing with changes in vehicle characteristics due to the factors such as varying velocity and road surface friction. In the study, a new design approach for the active front wheel steering system is proposed based on the Robust Model Matching (RMM) algorithm, which realizes desired frequency characteristics between the driver's steering angle and vehicle yaw rate. This makes the frequency characteristics robust for parameter errors and non linear dynamics. The effectiveness of the proposed system is verified by computer simulation of vehicle behavior running under various velocities and changing road surface friction coefficient. These results also suggest effectiveness of the control system when it is used for ITS (Intelligent Transportation Systems), because vehicles equipped with this steering system are easy to control by a higher layer control system.
